Ultimate "Dub" is by Sly and Robbie - they virtually invented it from a bass and drums point of view in studios in Jamaica with various producers.

Robbie Shakespeare is the bass player, Sly Dunbar the drummer - they are truly the founders in the Dub field! Look out for their stuff with King Tubby (Osbourne Ruddock) who was the first to make remixed B-sides out of Reggae singles with bass and drums to the fore - i.e. Sly n' Robbie.

Dub did originate with Reggae - so the producers like King Tubby and Lee Perry, would "Dub" or copy parts of a hit Reggae single, onto tape to make an instrumental version initially for the B-side - but these "re-mixes" became very popular in clubs.

So they would take a lot of instruments and all vocals out - usually just ending up with a skeleton track of bass and drums, with boosted low bass - then bring bits of the instruments back in, from the original mix - but altered through effects - mostly spacey echo and reverb.

Sometimes the bassist and drummer - liek Sly n Robbie would come back in and improvise looser, more prominent parts over the skeleton track - adding in drum crashes and percussion hits on massive reverb - but the main thing is a huge feeling of space that you get from this stripped down mix - so you have this huge but gentle, boomy bass - but then subtle high frequency sounds appearing to be at the edges of your hearing, almost outside your head....
